Q. Calculations for a standard VGA graphics screen?

Let's do the calculations for a standard VGA graphics screen (640×480) using 16 colours.

Total number of Pixels = 640 ×480 = 307200  

Colour Depth (16-colours) = 4   bits

Total minimum Memory = 1,228,800   bits

Total minimum memory (in bytes) = 153,600   bytes

                                                            153 KB  

Minimum Video RAM required and available = 256 KB.

So 16-colour VGA requires at least 153,600 bytes of memory however memory is only available in exponential powers of 2 therefore next highest available memory is = 256 KB.
